button and LED
Red The LED indicates what ha ppens when the button is
pressed.
If the LED is on (flashing or steady), pressing the button
silences the sounders.
If the LED is off, pressing the button activates the
sounders (if the control panel status and operating
mode allow manual activation of sounders).
The LED also indicates the status of the sounders:
• Steady
indicates that sounders are active (or will be
activated shortly)
• Flashing indicates that a delay is counting
(sounders are activated when the configured delay
elapses or when the delay is cancelled)
• Off indicates that the sounders are off (or will be
deactivated shortly)
To prevent the immediate silencing of sounders when
an alarm is first reported, the Sounder Start/Stop button
may be temporarily blocked when a configured
delay is counting down. For more information, see
“Sounders silence disab le ti me” on page 98.
Depending on the size of the installation, processing
commands to start or stop sounders may take a few
seconds to travel through the system. This is why, for

A steady red LED indicates that the output group
associated with the button is active. A flashing red LED
indicates that a delay is counting (the output group is
activated when the configured delay elapses or when
the delay is cancelled).
A flashing yellow LED indicates a fault. A steady yellow
LED indicates a disablement or a test.
Output group LED indications
The control panel can be configured to have several sounder, fire routing, or fire
protection output groups. Some groups may use the same indicators. When such
groups have the same status, that status is indicated. In the case of conflicting
status, the highest priority status is displayed.
Note: For evacuation panels, indications for output groups associated with the
programmable buttons use the corresponding programmable button LEDs.
The following examples illustrate this operation.
There are three sounder output groups, the first in fault status, the second in
delayed status, and the third in activated status. The sounder indications display
the fault status of the first group, the delay status of the second group, and the
activated status of the third group.

Chapter 1: Introduction

There are two fire routing output groups, the first is in activated status and the
second is in acknowledged status. The fire routing indication displays the
acknowledged status but not the activation status (the acknowledgement status
takes priority).

Cabinet installation
Where to install the control panel
Install the control panel in a location that is free from construction dust and
debris, and immune to extreme temperature ranges and humidity. See Chapter 5
“Technical specifications” on page 109 for mor e in for mation on the operating
temperature and relative humidity specifications.
Provide enough floor a nd wal l space to allow the control panel to be installed and
serviced without any obstructions.
The cabinet should be mounted so that the user interface is at eye level.
Note: This product has been certified to EN 54-2 using the standard wall
mounting installation method described below. If other mounting options are
used, take care to install the panel in an area that is not subject to excessive
vibration or shock.
Fixing the cabinet to the wall
Fix the cabinet to the wall using five M4 × 30 screws and five Ø 6 mm wall plugs,
as shown in Figure 7 below.
Figure 7: Mounting hole locations

Chapter 2: Installation
20 2X Series Installation Manual
To fix the cabinet to the wall:
1. Hold the cabinet to the wall at the required installation height.
2. Ensure that the cabinet is level using the built-in spirit level and mark drill
points on the wall.
3. Drill all required holes and insert a 6 mm wall plug into each.
4. Insert a screw in position (1) and hang the cabinet onto this screw.
5. Insert screws in positions (2) and tighten.
6. Insert screws in position (3) and tighten.
7. Tighten screw in position (1).

4] This kit contains a 3 m cable and the 2010-2-232-IB isolation board required for external
RS-232 device connections.
Other types of cable may be used subject to site-specific electromagnetic
interference (EMI) condi ti ons and ins tal l ation testing.
Using shielded loop cable
In most installations shielded loop cable is not required and the system has been
validated to operate in standard conditions with unshielded twisted-pair cable.
However, shielded cable provides more flexibility in solving site-specific EMI
problems and may be used, subject to following these guidelines:
• Use a multimeter to check that the shield is fully isolated from earth, the loop
positive, and the loop negative lines before connecting the shield to a single
point in the installation. The same isolation must be provided for any other
site wiring and loop cabling should avoid any known sources of EMI at the
site.
• Use the earth studs in the control panel cabinet (if you need to reduce
interference). See Figure 4 on page 17 or Figure 5 on page 18 for the location
of the earth studs.
The PCB terminal earthing connections only improve noise immunity in very
specific environmental conditions. In some cases, leaving the earth fully
isolated provides the best protection against EMI.
